How do you write under water?
An ordinary graphite pencil can be used to write and erasing is possible as well. What’s more, the AquaSketch’s surface is phosphorescent, which means it can illuminate notes during night dives. The vellum scroll is reusable, but you can replace it if need be.
Why pen is not used in space?
Regular pens that work on Earth did not work in space because they rely on gravity for the flow of ink to the nib. This was understood quite early by scientists and hence astronauts used pencils.
How does a zero gravity pen work?
Unlike most ballpoint pens, Fisher’s pen does not rely on gravity to get the ink flowing. The cartridge is instead pressurized with nitrogen at 35 pounds per square inch. This pressure pushes the ink toward the tungsten carbide ball at the pen’s tip. The ink, too, differs from that of other pens.

Can pens work in space?
NEED FOR A SPACE PEN Ordinary ball point pens did not work in space because the ink would not flow by gravity to the ball and the pen leaked if pressure was created in the ink reservoir (here). NASA used to use pencils, and in 1965 there was controversy over how much they spent on them.
Do normal pens work in space?
Here’s why astronauts can’t use regular ballpoint pens: Because ordinary pens rely on gravity. In space, of course, there isn’t enough gravity to force the ink out, so the pen’s reservoir needs to be pressurized.

Who discovered space pen?
In reality, the space pen was independently developed by Paul C. Fisher, founder of the Fisher Pen Company, with $1 million of his own funds. NASA tested and approved the pen for space use, especially since they were less flammable than pencils, then purchased 400 pens at $6 per pen.
How does an astronaut pen work?
The space pen works in numerous conditions: upside down, from -50oF to 400oF, in a vacuum, and underwater. The pressurized nitrogen also prevents the air and ink from mixing within the pen so that the ink does not evaporate before use. When the ballpoint moves, the gelatinous ink within the pen becomes liquid.
